V ooRNER JoINT FOR KNOCKDOWN SHOW-GASES AND OTHER STRUCTURES.

To all whom it may concern:

Be it known that I, INGVALD M. STORVIOK, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Corner-Joint for Knockdown Show- Cases and other Structures, of which the following is a specification.

My invention relates to knock-down joints for the corners of boxes, show cases, tables and other store and oiiice furniture, 620. And the main object is to provide a novel, cheap and efficient knock-down joint for the corners of such and other wooden structures.

In the accompanying drawing: Figure 1 is a top or plan view of a show case embodying my improved corner joint, of which one is exposed where one corner of the top or cover of the case is broken away. Fig. 2 is a front elevation of Fig. 1. Fig. 3 is a section on the line a ain Fig. 1 of the cover only, showing how the new joint may be employed also in the structure of a cover or other paneled section of furniture. Fig. at is an enlarged section on the line 6-?) in Fig. 2. Fig. 5 is a modification of Fig. &. Fig. 6 is a top view of one corner of a table frame embodying my invention.

Referring to the drawing by reference numerals, 1 designates the top or cover, 2 the bottom, 3 the front side, 4 the ends and 5 the rear side of a show case having glass panels 6 of any of the usual or other arrangements; the glass being usually placed against a solid molding 7 and held in place by a molding 8 secured in place by either nails or screws, so that it may be removed in case the glass gets broken and must be removed and replaced by a new one.

In Fig. 1 said molding 8 is shown as placed against the outer side of the glass while in Fig. 5 is shown that it may be placed against the inner side.

The vertical end rails or end pieces, 3 and 4: of the side and end sections are provided one with two angularly disposed ribs, 9 and 10, slidably fitted in corresponding grooves, 9F, 10*, in the adjacent other end piece. Said corner pieces, 3*, 1, may be secured on the upper and lower rails of each section by glue and dowel pins 11, or any other suitable means; or if the sections have no glass or other panels they may have their ends joined Specificationof Letters Patent.

together by my improved joint formed in the sections themselves without any special endpieces.

In Fig. 6 is shown how the rails 12 and 13 of a table frame may be oined to each table leg by. tenons or dowels 14:, each leg being made up of two sections 15, 16, the former having grooves 17 for ribs 18 of the other section to be slid into, whereby the sides and ends of the frame are made easily separable when the table is to be knocked down for storing or shipping. When the table is set up the leaf, (not shown) being secured to the frame by hooks or other means, (not shown) hold the frame sections to the leaf or top of the table and thereby also in the proper relative vertical position one to the other. In similar manner when the structure is a show case or boX or desk, the top and bottom, or one of them are secured to the jointed sections and prevents thereby any accidental sliding movement of the ribs in the grooves.

In Fig. 3 is shown how the rails or similar parts of any paneled frame or sash may be locked together by angularly disposed ribs 19 slipped into correspondingly formed grooves 20 and either detachably held together by a removable screw 21, or permanently by glue. In the latter case the ribs and grooves will prevent the parts from working loose from the glue and separate, as happens quite often where glue only is depended on to hold inserted ends of wood work in place.

I/Vhat I claim is:

1. In structures of the kind described, having fiat sections designed to be detachably joined together with their ends to form corners of the structure, cleats permanently secured across each of said ends of the sections, one of the adjacent cleats at each corner of the structure having two ribs one projecting edgewise substantially at right angles to the other, the other cleat having its adjacent portion providedwith two grooves arranged to receive said ribs when endwise inserted and thus interlock the cleats and thereby the sections.

2. In structures of the kind described, having flat sections designed to be detachably joined together with their ends to form corners of the structure, cleats permanently secured across each of said ends of the sections, one of the adjacent cleats at each corner of the structure having two ribs one projecting edgewise substantially at right angles to the other, the other cleat having its adjacent portion provided with tWo grooves I arranged to receive said ribs when endwlse inserted and thus interlock the cleats and thereby the sections, and means for holding the sections against accidental sliding move- 10 ment of the ribs in the grooves,

In testimony whereof I aflixiny signature.
